When histopathology on core biopsy reveals a higher-risk lesion, such as atypical lobular hyperplasia, excisional biopsy may be indicated to rule out malignancy. Epub 2012 Aug 31.

We found that 15 cases fulfilled the diagnostic criteria of CFA, in which 7 (46.7 %) had an FNA diagnosis of "suspicious for malignancy" or "indeterminate" while only 2 NCFA cases had that of "indeterminate" (p = 0.004).

IHC can aid in visualizing the myoepithelial layer. They fall under the broad group of adenomatous breast lesions. Stanford University School of Medicine Small capillary-like structures in the stroma. PMC In particular, these mutations are restricted to the stromal component. These tumors are usually benign, but they can come back and cause the breast to look abnormal if not totally removed.
